Abstract

Se relaciona con un método para sincronizar transceptores de radio y una disposición para llevar a la práctica dicho método en una red ad-hoc parasincronizar una multiplicidad de disposiciones de transceptores radiales con diferentescaracterís ticas que hacen uso de una interconexión aérea común.Cada disposición de transceptores comprende al menos dos transceptores que se comunican mutuamente a través de un enlace de transmisión radial. Todos lostransceptores se sincronizan auna senal d e sincronización común que comprende dos senales de impulso de radiobaliza en serie escalonados (TX1, TX2)que tienen la misma velocidad de repetición. Los transceptores sincronizan sus relojes control internos quecontrolan la transmi sión de la senal desdelos transceptores, a la más fuerte de las dos senales de impulso de radiobaliza en serie (TX1, TX2) escuchando durante uno de los conjuntos correspondientesde ventanas de tiempo (RX1, RX2). Entre larecepción de dos impulsos de radiobaliza, cada transceptor transmite impulsos de radiobaliza por sí mismo,contribuyendo de esta manera a la generación de la otra senal de impulso de radiobaliza en serie a la cual se puede enganchar los demástransceptores.It relates to a method for synchronizing radio transceivers and an arrangement for implementing said method in an ad-hoc network to synchronize a multiplicity of radio transceiver arrangements with different characteristics that make use of a common air interconnect. Each arrangement of transceivers it comprises at least two transceivers that communicate with each other through a radial transmission link. All transceivers are synchronized to a common synchronization signal comprising two staggered serial beacon pulse signals (TX1, TX2) having the same repetition rate. The transceivers synchronize their internal control clocks that control the transmission of the signal from the transceivers to the stronger of the two serial beacon pulse signals (TX1, TX2) by listening during one of the corresponding sets of time windows (RX1, RX2). ). Between receiving two beacon pulses, each transceiver transmits beacon pulses on its own, thereby contributing to the generation of the other serial beacon pulse signal to which the other transceivers can latch.
